# Which falls faster?

If you drop two balls from somewhere really high, the same shape and size but one is heavier (lets say metal) and the other is lighter (lets say plastic). Which falls the fastest? And why?

Don't google it! I just want to see how many people know it :)

• Metal falls faster!
Vote A
• Plastic falls faster!
Vote B
• They fall the same speed!
Vote C
• My brain hurts >.<
Vote D

Okay, so the answer is actually the metal one, but only by a tiny bit because of buoyancy. In a vacuum they would fall at the same speed. Many people think the metal will fall faster simply cause it has a bigger force pulling it down. Then there are many people who remember learning that they actually fall the same speed, because g=W/m=9.8m/s^2, the force is stronger but it needs more force to accelerate. But very few people seem to know that that's only in a vacuum and in air the heavy one does
fall faster. And out of those few people most think it's cause of air resistance, which doesn't matter because they're the same shape and size. So the real reason is buoyancy, it's what makes things float. And an easy way to see this is dropping a balloon full of air and a balloon full of water. Or a balloon full of helium works even better.
So thanks all for your responses :) Hope you learned something interesting :)
